A Long Island real-estate agent is turning the mortgage-crisis fallout into donations for a local charity.

David Farrell, owner of a real-estate brokerage in Mineola, N.Y., will donate $5 from every $50 ticket sold from buyers’ bus tours of foreclosed homes for sale in Long Island to Hour Children, a charity in St. Rita’s Convent in Long Island City, where nuns care for children whose parents are in prison, reports Newsday.

Mr. Farrell, who has previously appraised properties for the Roman Catholic Diocese of Brooklyn, N.Y., hopes to raise $50,000 this year.
